The compressor 304 is connected to the condenser 302, and the outdoor fan 303 can blow air towards the condenser 302 and the connecting air duct 200 between the indoor and outdoor units. The outdoor fan 303 blows air in the direction of the condenser 302 and the connecting air duct 200 between the indoor and outdoor units, so that a part of the air can be sent into the indoor unit 100. The on-off damper 105 can control the air to enter the indoor unit 100 through the connecting air duct 200 between the indoor and outdoor units. The fresh air supply system is in the outdoor unit 300, thus avoiding indoor noise. The compressor 304 compresses the low-pressure and low-temperature refrigerant vapor into high-pressure and hot vapor to provide power for the refrigeration cycle. The function of the condenser 302 is to cool and condense the high-pressure and hot vapor output by the compressor 304 into high-pressure liquid refrigerant. During the condensation process, the refrigerant will release heat, and the outdoor fan 303 can play a role in dissipating heat from the condenser 302, which can save the user's investment cost and has a certain energy-saving effect.

[0032] As Figure 1As shown, in some embodiments, the outdoor unit 300 is provided with an outdoor unit air supply opening 301, and the indoor-outdoor connection air duct 200 is communicated with the outdoor unit air supply opening 301. The fresh air blown by the outdoor fan 303 towards the indoor-outdoor connection air duct 200 enters the indoor-outdoor connection air duct 200 through the outdoor unit air supply opening 301. The connection mode between the outdoor unit air supply opening 301 and the indoor-outdoor connection air duct 200 facilitates the maintenance and cleaning of the outdoor unit 300 and helps to maintain the long-term stable operation of the system.

[0033] As Figure 1 shown, in some embodiments, the outdoor fan 303 includes a first driving member and a first fan, and the first driving member is connected to the first fan. The first driving member is usually a motor, which can provide power for the first fan, ensure that the fan rotates efficiently, generate sufficient wind power to meet the air flow requirements of the air conditioning system, and by controlling the rotation speed of the first driving member, the wind power of the first fan can be adjusted, so as to achieve precise control of the output wind power of the outdoor fan 303.

[0034] As Figure 1 shown, in some embodiments, an indoor fan 103 and an evaporator 102 are installed in the indoor unit 100. The indoor fan 103 can blow air towards the evaporator 102, and an air return damper 104 is provided on the indoor unit 100. When the switch damper 105 is opened, air can enter the indoor unit 100 through the indoor-outdoor connection air duct 200, and the air return damper 104 of the indoor unit 100 can generate indoor air return. In this way, the outdoor air enters the indoor unit 100, mixes with the indoor air return, is cooled and dehumidified, and then enters the room. By mixing the indoor air return and the outdoor fresh air, the complete dependence on the outdoor fresh air can be reduced, thereby reducing the energy consumption of the system.

[0035] As Figure 1 shown, in some embodiments, the indoor fan 103 includes a second driving member and a second fan, and the second driving member is connected to the second fan. The second driving member provides power for the second fan, ensures that the fan rotates efficiently, quickly circulates the indoor air, improves the efficiency of the air conditioning system, adjusts the fan speed according to the actual requirements of the indoor temperature and humidity, and avoids excessive cooling or heating, thereby saving energy.

[0036] As Figure 1 shown, in some embodiments, an indoor unit air outlet 101 is provided on the indoor unit 100. When the air conditioning unit is operating normally, the outdoor air enters the indoor unit 100, mixes with the indoor air return, is cooled and dehumidified by the evaporator 102, and then is sent into the room through the indoor unit air outlet 101. When the air conditioning unit is not started, a part of the air enters the indoor unit 100 from the outdoor unit air supply opening 301 through the indoor-outdoor connection air duct 200 and is sent into the room through the indoor unit air outlet 101.

[0038] As Figure 1 shown, in some embodiments, the evaporator 102 communicates with the compressor 304. The compressor 304 compresses the low-pressure and low-temperature refrigerant vapor into high-pressure and hot vapor, and then transports it to the condenser 302. The evaporator 102 absorbs the indoor heat to evaporate the refrigerant, thereby achieving refrigeration.

[0039] The working principle and process of an outdoor fresh air supply air conditioner unit of the present utility model: The outdoor fan 303 blows air towards the condenser 302 and the indoor and outdoor connection air duct 200, so that a part of the air can be sent into the indoor unit 100. The on-off air valve 105 can control the air to enter the indoor unit 100 through the indoor and outdoor connection air duct 200. During the condensation process, the refrigerant will release heat, and the outdoor fan 303 can play a role in dissipating heat from the condenser 302. The outdoor air enters the indoor unit 100 and can be mixed with the indoor return air and then pass through the evaporator 102 to be cooled and dehumidified and then sent into the room through the indoor unit air outlet 101.

The outdoor fan 303, the compressor 304, the on-off air valve 105 are turned on, the return air valve 104 is turned off, and the indoor fan 103 is turned off. The air sent from the outdoor unit 300 exchanges heat with the low-temperature and low-pressure refrigerant passing through the evaporator 102, and the outdoor air is cooled and dehumidified and then sent into the room. The dotted line with an arrow represents the operation of the compressor 304 and the refrigerant starts to circulate.

[0044] Embodiment 3

[0045] As Figure 4 shown, in this embodiment, when the air conditioner unit is operating normally, that is, the compressor 304, the outdoor fan 303, and the indoor fan 103 are all turned on, and fresh air needs to be supplemented indoors, the switch air valve 105 and the return air valve 104 are directly opened, and the outdoor air enters the indoor unit 100, is mixed with the indoor return air, is cooled and dehumidified after passing through the evaporator 102, and is sent into the room through the air outlet 101 of the indoor unit.
